Struct StoreInventory 

pub struct StoreInventory {
    pub root: PathBuf,
    pub entries: BTreeMap<String, StoreEntry>,
}

Walked store inventory — every entry under the source root, keyed by basename for O(1) lookup. Operators query by name pattern, by file-count, by size, etc.

Fields

root: PathBuf

Source root.

entries: BTreeMap<String, StoreEntry>

Entries keyed by basename.

Implementations

impl StoreInventory

pub fn walk(profile: &StoreInventoryProfile) -> Result<Self, SpecError>

Walk the source root once, build a typed inventory per the supplied profile.

Errors

• inventory-bad-root if the source root doesn’t exist.
• inventory-bad-pattern if the skip regex doesn’t compile.
• inventory-io for filesystem failures.

pub fn get(&self, name: &str) -> Option<&StoreEntry>

Lookup by basename.

pub fn filter_by_name( &self, pattern: &str, ) -> Result<Vec<&StoreEntry>, SpecError>

Filter entries by name regex.

Errors

Returns inventory-bad-pattern if the regex doesn’t compile.

pub fn filter_by_size( &self, predicate: impl Fn(u64) -> bool, ) -> Vec<&StoreEntry>

Filter entries by file_count predicate.

pub fn total_size(&self) -> u64

Total size summed across all entries.

pub fn total_files(&self) -> usize

Total file count summed across all entries.
